Ideal Exalt Floor Combi 199 in practice
The Exalt Floor Combi 199 is the top of the Exalt combi range. Heating input runs 24,875 to 199,000 BTU/h at 95% AFUE with an 8:1 turndown, a 184 MBH DOE heating capacity and a 159 MBH AHRI net rating. Its published DHW delivery — 5.3 GPM at a 70°F rise, 4.9 GPM at 75°F and 4.6 GPM at 80°F — is the highest in the Exalt family, matching the wall combi 199.
The floor chassis measures 22 x 41 x 22 inches, weighs 191 lb and holds 4 gallons, with the Caleffi 548 series separator with air elimination and a pre-installed internal circulator included. Venting is 3-inch up to 100 equivalent feet; the 2-inch option appears on the combi 155 only. The DHW maximum is 150°F (65°C) and the maximum DHW pressure is 150 psi.
CTRLMax provides DHW priority, outdoor reset and plain-text diagnostics. The model is intended for larger homes with a mechanical-room floor where one appliance can cover both space heating and hot water; the published submittal documents it for specification. Natural-gas (IDEXFS199C) and propane (IDEXFS199CLP) versions are published. No explicit Canadian sales statement was found on the official pages checked on 2026-09-09; the Exalt and Gallant submittals list ANSI Z21.13 and CSA 4.9 compliance, so Boilers.ca records canadianStatus as unknown.
Best suited to
- Larger homes wanting one floor-standing appliance for heat and hot water
- Households needing the full 5.3 GPM DHW delivery at a 70°F rise
- Installations that value factory-mounted separation and circulation
